TOOL FOR BRUSH-MAKERS.

SPECIFICATION forming part of Letters Patent No. 759,465, dated May 10, 1904.

Application filed July 17, 1903.

T0 cti/Z whom t may concern:

Beit known that I, HENRY NIELsoN, a subject of the King of Denmark, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Tools for Brush-Makers, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying' that principle, so as to distinguish it from other inventions.

My invention relates to tools for brushmakers, and particularly to such tools as are employed in fastening the bristles to the liandle or back of the brush, its object being to provide an efficient and economical device for the purpose set forth.

The annexed drawings and the following description set forth in detail certain means embodying the invention, such disclosed means constituting but one of Various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a perspective View of a device embodying my invention with a wire used for fastening bristles contained therein, and Fig. II, represents a longitudinal sectional view of said device with the wire therein.

rThe device embodying my invention consists of a handle A, of copper or other suitable material, a long metallic needle B, one end of which is fastened in the handle A so as to extend out longitudinally from said handle, as shown in Fig. II, and a clamping-lever C, mounted upon said handle by means of a pin l running transversely through the latter and upon which pin said clamping-lever is oscillatory for a certain distance, as will be hereinafter explained. The handle A consists in the device illustrated of two semicylindrical pieces a and c2, assembled by placing their fiat surfaces so that they abut each other, thus forming a cylindrical handle, as shown. One

of said pieces a is slotted vertically to receive the head o of the clamping-lever C, which head is fastened within the slot@ by means of a pin Z passing transversely through the piece c Serial No. 165,948. (No model.)

laterally of the slot. The bottom of the head c is provided with a cam or eccentric surface c, which may be caused to intersect a passage-way as, as hereinafter described. It is thus seen that the lever C has free play upon the pin el, which play is limited by the ends of the slot e and the eccentricity of the bottom of the head c. The flat surfaces of the semicylindrical pieces a and e2 are furrowed, so as to form when said pieces are assembled a passage-way a3 through the handle A through which a wire may be passed. The clamping-lever C is so fastened to the handle A that its head c exerts no pressure upon the wire when there is no pressure brought to bear upon the lever C. The needle B is pointed at its outer end to enable its easy passage through the perforations in the handle of a brush and is also provided with a small eye through which the wire may be passed. Opposite said slot e is secured a flat piece D, of hard steel, having a serrated biting-surface d.

The operation of my device is as follows: The wire E is threaded from a spool or any other suitable source (not shown) through the passage-way c3 and the eye b. The pointed end of the needle is then passed through a perforation in a brush back or handle, from rear to front of said back, and tufts of bristles are looped within that part of the wire projecting from the eye 7) in a manner Well known to those skilled in the art. The needle is then withdrawn from the perforation, bringing with it to the rear of the brush-back the bristle tufts, which are looped within the wire, the tension of the wire being maintained by holding down tight with the hand the lever c of the clamping device C, whereby the head o bears down upon the wire E, clamps it upon the piece I), and prevents it from slipping. 'Ihe bristle tufts having been withdrawn to the rear of the brush-back, they are fastened and the needle is passed through another perforation of the brush-back, the pressure upon the lever c having been relaxed, so as to enable the easy feed of the wire required. A bristle tuft is again looped within the wire and the process repeated, as hereinbet'ore described.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the means herein disclosed, provided the means stated by the following claim or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- In a tool for brush-makers, the combination of a handle, a recessed portion in said handle, a serrated member below said recess and running longitudinally of said recess and handle, a guiding-needle for Wire mounted in said handle, a passage-Way for Wire running
